IMPROVEMENT IN BALlNG-PRE SSES.

Specification forming part of Letters Patent No. 139,849, dated J une 17,1873; application filed May 5, 1873.

A patent No. 84,982, granted me December 15,

1868, the object of which improvement is to provide an easy and efficient method of uniting together the parts composing the pedestal, and also to provide a simple and reliable connection between the pedestal and the box for y the material to be baled, and lessen the strain on the pedestal.

Figure l is a vertical section through W W. Fig. 2 is a horizontal section through A is a screw formed as described in my patent 84,982 5 this passes throughsuitably formed spaces in the base-plate C, and crown or cap plate D; between these plates are placed two hollow columns of any form that can with the screw A be placed inside therevolving nut B. Preferably, however, these columns are made of the form, and occupy the position, shown by H H, their outer surfaces conforming to the inside of the nut B, and their inner surfaces conforming to the shape of the screw A, for when so made their outer surfaces become a portion of a cylinder on which the nut B revolves, and their inner surfaces a guide for the screwA in passing up.

and down between them. The hollow spaces within these columns are to receive the bolts E E. The bolts E E are ordinary bolts with a nut on each end, and at a proper distance between these nuts is a fixed collar, F. These bolts below the collar F pass firstthrough the cap-plate D, next through the columns H H, and finally through the base-plate C, the end of the bolt projecting through receiving the nut L. It is evident that when this nut L is screwed up it will unite the various parts composing the pedestal firmly together. Above the collar F these bolts extend upward through the lower beams G G of the cotton-box or box for containing the material to be packed, and

receive the nuts PP. Itis evident that when these nuts are screwed down they will secure the beams G G firmly to the top of the pedestal. In addition to the above-named offices these bolts E E perform a third and very important office, as will be seen. Since these bolts form the only connection between the packing-box and the pedestal above described, they must receive the entire force exerted by the screw A when working. This strain they convey within the nut B, entirely through the pedestal, and transfer it to the under side of the base-plate C, so that the room inside of the nut to allow of the passing through on each side of the 'screw of more than one bolt, it may be found advantageous to use more than a single bolt. I do not, therefore, confine myself to theuse of a single bolt, as shown, but elect to use two or v pass through thepedmore bolts when the, estal inside the nut as described.

The use of the columns H H, though of great advantage to the eificient'working of the nut B, are not indispensable, as the upper and lower plates form asufficient guide for the screw A in moving up and down, and the bolts E E may pass through the inside of the nut B, on each side of the screw A, as well without as with these columns. I do not design, therefore, to confine myself exclusively to the arrangement requiring the use of these colurnns. i

I claim as my invention l. The base-plate C and cap-plate D of the pedestal surrounding the screw A, connected together by means of twoor more bolts passing from one to the other through the inside of the revolving nut B, substantially as described.

2. The bolts E E provided with the collar F;

the portion below the collar connecting the parts of the pedestal together; the portion above the collar serving toc'onnect the pressbox to the pedestal and the whole bolt as a means of transferring the strain of pressing below the nut B, substantially as described.

3. The columns H H within the nut B,when made with bolt-holes suited to the reception and passage through them of the bolts EE, connecting together the plates C and D, substantially as described.
